Description
本発明は、沸き上げた湯水を貯湯タンクに貯湯する貯湯式給湯機に関するものである。 The present invention relates to a hot water storage type water heater that stores hot water in a hot water storage tank.
従来の貯湯タンクを有するヒートポンプ給湯機は、圧縮機、水冷媒熱交換器、空気冷媒熱交換器、減圧手段を順次接続した閉回路で冷媒を循環させる冷媒循環回路と、この水冷
媒熱交換器で加熱された温水を貯蔵する貯湯タンクとを一つの筐体内に収納して構成していた。また、上記給湯機は、昼間使用する湯量を夜間のうちに沸かし貯蔵していたが、貯湯タンクからの放熱損失が問題となっていた。
A heat pump water heater having a conventional hot water storage tank includes a compressor, a water refrigerant heat exchanger, an air refrigerant heat exchanger, a refrigerant circulation circuit that circulates refrigerant in a closed circuit in which pressure reducing means are sequentially connected, and the water refrigerant heat exchanger. The hot water storage tank for storing the hot water heated in the above is housed in a single housing. Moreover, the hot water heater boiled and stored the amount of hot water used during the daytime, but there was a problem of heat dissipation loss from the hot water storage tank.
そこで、貯湯タンクの周囲に真空断熱材を設置していた。真空断熱材は、単一あるいは複数の真空層を内部に有する構成であって、熱を伝えやすい空気層が存在しないことから高い保温力が得られるものである（例えば、特許文献１参照）。
ところで、上記のような冷媒循環回路と貯湯タンクとを一つの筐体内に収納するようなヒートポンプ給湯機において、貯湯タンクを筐体の後ろ側に配置するとともに配管類を貯湯タンクの前方側に配置するようにして、機器のメンテナンス性を高めていた。 By the way, in the heat pump water heater in which the refrigerant circulation circuit and the hot water storage tank as described above are housed in one housing, the hot water storage tank is disposed on the rear side of the housing and the piping is disposed on the front side of the hot water storage tank. As a result, the maintainability of the equipment was improved.
しかし、貯湯タンクの高さ方向に略均等に配置されている温度サーミスタが不良となり交換を行なわなければならない場合には、貯湯タンクが筐体の後ろ側に配置されているため配管類が邪魔となり、サーミスタが取り扱いづらくなっていた。 However, if the temperature thermistor arranged approximately evenly in the height direction of the hot water tank is defective and must be replaced, the piping is obstructed because the hot water tank is located on the rear side of the housing. The thermistor was difficult to handle.
さらに、貯湯タンクの周囲に真空断熱材が配置されている場合は、配管類を筐体からすべて取り外し、貯湯タンクを筐体から取り出し、貯湯タンクから真空断熱材をすべて剥ぎ取った上でサーミスタの交換を行い、その後は新たな真空断熱材を貯湯タンクに設置し、筐体に貯湯タンクを設置した後に配管類を取り付けていた。 In addition, if vacuum insulation is placed around the hot water tank, remove all piping from the housing, remove the hot water tank from the housing, remove all vacuum insulation from the hot water tank, After the replacement, new vacuum insulation was installed in the hot water storage tank, and the piping was attached after the hot water storage tank was installed in the housing.
このように、サーミスタの交換に際しては極めて複雑な作業工程を行わなければならなかった。なお、ガラスウールやスチロール等を材質とする断熱材ではサーミスタ設置箇所近傍に切り込みを入れて部分的に取り出すことも可能であったが、真空断熱材はその内部に真空層を形成することによって保温力を保っているものであり、真空断熱材自体に切り込みを入れることはできない。 As described above, when the thermistor is replaced, an extremely complicated work process has to be performed. Insulation materials made of glass wool or styrene could be partially cut out by cutting in the vicinity of the thermistor installation location, but vacuum insulation materials are insulated by forming a vacuum layer inside them. It keeps power and can't cut into the vacuum insulation itself.
前記従来の課題を解決するために、本発明の貯湯式給湯機は、加熱手段により加熱した湯水を貯湯する貯湯タンクと、前記貯湯タンクの高さ方向に複数配置された温度サーミスタと、前記貯湯タンクの側面部分を覆う真空断熱材と、前記貯湯タンクの天井部断熱材と底部断熱材とを連通し、前記貯湯タンクを覆い、真空断熱材を構成する材質と異なる材質から形成され、かつ、前記温度サーミスタを覆う取出部を設けた連通断熱材とを備えたことを特徴とするものである。 In order to solve the above-described conventional problems, a hot water storage type water heater of the present invention includes a hot water storage tank for storing hot water heated by heating means, a plurality of temperature thermistors arranged in a height direction of the hot water storage tank, and the hot water storage. A vacuum heat insulating material covering a side surface portion of the tank, and a ceiling heat insulating material and a bottom heat insulating material of the hot water storage tank are communicated, the hot water storage tank is covered, and is formed of a material different from a material constituting the vacuum heat insulating material, and And a communication heat insulating material provided with an extraction portion that covers the temperature thermistor .
これによれば、切り込みを入れることができない真空断熱材を貯湯タンクの周囲に用いた場合であっても、温度サーミスタの交換時に大掛かりな作業工程を必要とすることがない。 According to this, even when a vacuum heat insulating material that cannot be cut is used around the hot water storage tank, a large work process is not required when the temperature thermistor is replaced.
本発明によれば、貯湯タンクの側面部分を真空断熱材で覆い、切り込みを入れることができない真空断熱材を貯湯タンクの周囲に用いた場合であっても、温度サーミスタの交換時に大掛かりな作業工程を必要とすることがない貯湯式給湯機を提供できる。 According to the present invention, the side portions of the hot water storage tank have covered with the vacuum heat insulating material, even in the case of using the vacuum heat insulating material which can not be put off interrupt around the hot water storage tank, large scale when replacing the temperature thermistor It is possible to provide a hot water storage type hot water heater that does not require a complicated work process.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.
（実施の形態１）
以下本発明の一実施例によるヒートポンプ給湯機について説明する。
(Embodiment 1)
Hereinafter, a heat pump water heater according to an embodiment of the present invention will be described.
図１は、本実施例によるヒートポンプ給湯機の概略構成を示す斜視図、図２は同ヒートポンプ給湯機の内部配置を示す正面図、図３は貯湯タンクと貯湯タンクに設けられた断熱材を示す図である。 FIG. 1 is a perspective view showing a schematic configuration of a heat pump water heater according to the present embodiment, FIG. 2 is a front view showing an internal arrangement of the heat pump water heater, and FIG. 3 shows a hot water storage tank and a heat insulating material provided in the hot water storage tank. FIG.
まず、特に図１及び図２を用いて全体構成について説明する。 First, the overall configuration will be described with reference to FIGS.
本実施例によるヒートポンプ給湯機は、立方形状からなる筐体１０内部に、冷媒循環回路２０と貯湯タンク３０とを有している。 The heat pump water heater according to this embodiment includes a refrigerant circulation circuit 20 and a hot water storage tank 30 inside a cubic housing 10.
筐体１０内部は、仕切り板１１によって左右方向に２つの空間が形成され、一方の空間に冷媒循環回路２０が配置され、他方の空間に貯湯タンク３０が配置されている。 Inside the housing 10, two spaces are formed in the left-right direction by the partition plate 11, the refrigerant circulation circuit 20 is disposed in one space, and the hot water storage tank 30 is disposed in the other space.
冷媒循環回路２０は、圧縮機２１、水冷媒熱交換器２２、空気冷媒熱交換器２３、減圧手段（図示せず）を順次接続し、冷媒を循環させる閉回路で構成されている。なお、この冷媒としては二酸化炭素冷媒を用いるものが好ましい。 The refrigerant circulation circuit 20 is configured by a closed circuit in which a compressor 21, a water refrigerant heat exchanger 22, an air refrigerant heat exchanger 23, and a decompression means (not shown) are sequentially connected to circulate the refrigerant. In addition, what uses a carbon dioxide refrigerant as this refrigerant | coolant is preferable.
ここで圧縮機２１及び水冷媒熱交換器２２は、支持板１２上に設置されている。空気冷媒熱交換器２３は、筐体１０の一方の空間の後方面及び側面を覆うように平面視で略Ｌ字状に配置されている。また、筐体１０の一方の空間には、複数のファン２４、２５が配置されている。これらのファン２４、２５によって、空気冷媒熱交換器２３での熱交換を行う。 Here, the compressor 21 and the water-refrigerant heat exchanger 22 are installed on the support plate 12. The air refrigerant heat exchanger 23 is arranged in a substantially L shape in plan view so as to cover the rear surface and the side surface of one space of the housing 10. A plurality of fans 24 and 25 are arranged in one space of the housing 10. These fans 24 and 25 perform heat exchange in the air refrigerant heat exchanger 23.
支持板１２の下面には、筺体１０を設置面に設置するための筺体支持脚１３が設けられている。 On the lower surface of the support plate 12, a chassis support leg 13 for installing the chassis 10 on the installation surface is provided.
また、貯湯タンク３０の下部には、支持板１２との間を連結するタンク支持脚３１が設けられている。 In addition, tank support legs 31 are provided below the hot water storage tank 30 to connect to the support plate 12.
また、貯湯タンク３０の前方下部分に、貯湯タンク３０に水を供給する給水管３２、貯湯タンク３０のお湯を外部に導出する給湯管３３、風呂追い炊き用給湯管３４、及び風呂追い炊き用給水管３５をそれぞれ接続する接続弁３２Ａ、３３Ａ、３４Ａ、３５Ａを配置している。貯湯タンク３０の前方下部分に位置する支持板１２は、他の面よりも高い位置に設けることで、貯湯タンク３０の前方下部分には、接続弁３２Ａ、３３Ａ、３４Ａ、３５Ａが配置される空間を形成している。なお、図１においては、これらの接続弁３２Ａ、３３Ａ、３４Ａ、３５Ａを省略している。 In addition, a water supply pipe 32 that supplies water to the hot water storage tank 30, a hot water supply pipe 33 that leads the hot water of the hot water storage tank 30 to the outside, a hot water supply pipe 34 for bath reheating, and a bath reheating service Connection valves 32A, 33A, 34A and 35A for connecting the water supply pipes 35 are arranged. The support plate 12 located in the lower front part of the hot water storage tank 30 is provided at a position higher than the other surfaces, and the connection valves 32A, 33A, 34A, 35A are arranged in the lower front part of the hot water storage tank 30. A space is formed. In FIG. 1, these connection valves 32A, 33A, 34A, and 35A are omitted.
次に、特に図３を用いて貯湯タンク３０の構成について説明する。貯湯タンク３０は、４つの断熱材により覆われており、貯湯タンク３０の側面を覆う真空断熱材４１と、貯湯タンク３０の天井部分を覆う断熱材４２と、貯湯タンク３０の底部分を覆う断熱材４３と、貯湯タンク３０の高さ方向に略均等に配置された複数の温度サーミスタ４０と、その温度サーミスタ４０を覆うようにして連通断熱材４５上に取出部４６を設けている。なお、真空断熱材４１以外の断熱材４２、４３、４５、４６はスチロールやガラスウール等を材質とする。 Next, the configuration of the hot water storage tank 30 will be described with reference to FIG. The hot water storage tank 30 is covered with four heat insulating materials, a vacuum heat insulating material 41 covering the side surface of the hot water storage tank 30, a heat insulating material 42 covering the ceiling portion of the hot water storage tank 30, and a heat insulating material covering the bottom portion of the hot water storage tank 30. A material 43, a plurality of temperature thermistors 40 arranged substantially evenly in the height direction of the hot water storage tank 30, and an extraction portion 46 are provided on the communication heat insulating material 45 so as to cover the temperature thermistors 40. The heat insulating materials 42, 43, 45 and 46 other than the vacuum heat insulating material 41 are made of styrene or glass wool.
そして、メンテナンス時にはその取出部４６から温度サーミスタ４０を取り出して交換等の作業を行うことができる。 During maintenance, the temperature thermistor 40 can be taken out of the take-out portion 46 and replaced.
なお、取出部４６は図４に示したように、連通断熱材４５と同じ材質の断熱材を単数または複数詰め込む構成として保温効果を高めても良いし、あるいは開閉自在となる構成としてもよく、温度サーミスタ４０を覆うような構成であれば上記以外の構成であってもよい。 In addition, as shown in FIG. 4, the extraction part 46 may have a heat insulation effect as a structure in which one or more heat insulating materials of the same material as the communication heat insulating material 45 are packed, or may be configured to be openable and closable. Any other configuration may be used as long as it covers the temperature thermistor 40.
また、図３、図４に示した形態以外にも、例えば図５に示すように真空断熱材４１の途中であって、温度サーミスタ４０の設置箇所に取出部４６を設けてもよく、真空断熱材４１成形時にこのような取出部４６を形成しておけば、簡単に温度サーミスタ４０を取り出して交換等の作業を行うことができる。 In addition to the forms shown in FIGS. 3 and 4, for example, as shown in FIG. 5, an extraction portion 46 may be provided at the location where the temperature thermistor 40 is installed in the middle of the vacuum heat insulating material 41. If such an extraction portion 46 is formed at the time of molding the material 41, the temperature thermistor 40 can be easily taken out and replaced or the like.
以上のように、本実施の形態によれば、メンテナンス時に取出部４６を通じて温度サーミスタ４０が取り出せるので、切り込みを入れることができない真空断熱材を貯湯タンクの周囲に用いた場合であっても、温度サーミスタの交換時に大掛かりな作業工程を必要とすることがない。 As described above, according to the present embodiment, since the temperature thermistor 40 can be taken out through the take-out portion 46 at the time of maintenance, even when a vacuum heat insulating material that cannot be cut is used around the hot water storage tank, There is no need for a large work process when replacing the thermistor.
また、取出部４６を真空断熱材でなくスチロールやガラスウール等とすることによって、温度サーミスタ４０と取出部４６が接触しても性能に影響がなく、真空断熱材の破れにより断熱効果が低下することを防止できる。 Moreover, by making the extraction part 46 into a styrene or glass wool instead of a vacuum heat insulating material, even if the temperature thermistor 40 and the extraction part 46 come into contact with each other, the performance is not affected, and the heat insulation effect is reduced due to the breakage of the vacuum heat insulating material. Can be prevented.
また、図３のように連通断熱材４５に取出部４６を設ける構成とすることによって、取出部４６による隙間が生じにくくなり、保温効果が低下することなく、放熱損失を抑制できる。なお、図５に示したように真空断熱材４１の途中に取出部４６を設けても良いが、真空断熱材４１は比較的柔軟性がないため、真空断熱材４１と取出部４６との間に隙間を生じやすくなる。 Moreover, by setting it as the structure which provides the extraction part 46 in the communication heat insulating material 45 like FIG. 3, it becomes difficult to produce the clearance gap by the extraction part 46, and can suppress a heat dissipation loss, without reducing a heat retention effect. As shown in FIG. 5, the extraction part 46 may be provided in the middle of the vacuum heat insulating material 41. However, since the vacuum heat insulating material 41 is relatively inflexible, the space between the vacuum heat insulating material 41 and the extraction part 46. It becomes easy to produce a gap.
本発明は、お風呂への給湯、沸き上げ機能を備えたヒートポンプ給湯機の他、暖房、乾燥機能を備えたヒートポンプ給湯機として利用することができる。また、ヒートポンプを熱源とする給湯機に限らず、電気ヒーターを熱源とする給湯機であっても適用できる。 INDUSTRIAL APPLICABILITY The present invention can be used as a heat pump water heater having heating and drying functions in addition to a hot water heater and a heat pump water heater having a boiling function. Further, the present invention is not limited to a water heater using a heat pump as a heat source, but can be applied to a water heater using an electric heater as a heat source.
